AN7511, AN7511S
1-W BTL audio power amplifier
I Overview
The AN7511 and AN7511S are the audio power am-
plifier ICs with 1-ch output. The BTL (Balanced Trans-
former-Less) method can provide fewer external parts and
more easy design for applications.
I Features
• 1-W output (8 Ω) with supply voltage of 5 V: AN7511
• 0.5-W output (16 Ω) with supply voltage of 5 V: AN7511S
• On-chip standby function
• On-chip muting function
I Applications
• Televisions, radios, and personal computers
